Exclamation using a s5 tps on a s4 for the s-afc

Has anyone done this yet. I need info on how to hook up the s-afc in my s4 t2 so that it reads the throttle position right and is effective. If anyone has any ideas or has got theirs to work then please let me know. I was told to use the s5 t2 tps to get it to work right. then what setting does it need to be on 05 05 or 06 06. PLEASE LET ME KNOW.

The S5 TB has no lever to work the S4 MOP, so it takes some fabricating to make it work.

The in/out setting is for the AFM and is not a TPS factor.

The best option is to tap the gray THR wire to the signal from the pressure sensor instead of the TPS.
That way you get to the high map on high boost regardless of TPS value.
(Think about how the boost shoots up at light throttle on cold mornings.)
